This book is a wonderful meditation manual, based on the annotated translation of the 14th century Tibetan book 'The Precious Copper Letters' by Longchenpa, a key book in the teaching of Buddhist meditation that breaks down the 'seven mental trainings' of Dzogchen Buddhism. Longchenpa's sevenfold mental training is aimed at awakening awareness and inner vision. In this volume, the well-known Rice University professor of Philosophy of Religion and Tibetologist Anne C. Klein explains these Longchenpa trainings beautifully, clearly and simply, making them accessible and easy for anyone in the West interested in cultivating a clear, compassionate and wisemind. The author dives into the teachings of sutra, tantra and Dzogchen, to resolve our questions about what awakening entails and how it relates to the truth of our human condition in this moment.
